Deris, since 1912, has been one-stop shop for IP services with one of the largest and internationally regarded IP prosecution and advisory team in Turkey. 

The firm has been a pioneer in shaping the IP landscape by obtaining the precedent decisions and participating the preparation of the IP legislation upon the invitation of the legislative bodies. Deris provides a wide spectrum of high-quality services that are essential for securing, maintaining and enforcing IP rights. 

The firm’s services and counseling are supported by the trademark attorneys and technical experts, who are national and European patent attorneys, under a unique service approach combining long-standing enforcement experience with prosecution-technical expertise. The firm’s goal is to secure enforceable IP rights in the market so that they can be transformed into sustainable commercial values.

Today, Deris consists of two legal entities: Deris Patents & Trademarks Agency A.S., which counsels, files, prosecutes, registers and manages IP rights worldwide; and Deris Attorney-At-Law Partnership, which provides legal counseling in contentious and non-contentious matters and representation for litigation before IP, civil and commercial courts.

The Team consists of 25 attorneys at law and 27 registered trademark and patent attorneys and 6 European Patent attorneys. With the administrative and support staff in the trademark, search, design patent, patent and litigation departments, the firm has more than 80 employees.
